“It is a custom PCB designed to drop directly into the Z80 DIP-40 CPU socket of any legacy Z80-based computer. Rather than using a discrete #Z80 processor, the board hosts an RP2350B microcontroller — a dual-core 150MHz Cortex-M33 device capable of running at up to 300MHz — whose programmable I/O (PIO) state machines take full, cycle-accurate control of the Z80 address, data, and control buses.” Basically an ICE with Wi-Fi. #RP2350 #electronics #hardware #retrocomputing

SGS Thompson, Siemens, many of the Japanese semiconductor companies, etc. But I'm not aware of any still manufacturing it. Zilog may have been the last.” #retrocomputing

on 02021-01-20Axe Parser recommended by lwb on the orange website: “If they have a TI-83 or TI-84 graphic calculator, you can't beat Axe Parser! It's as simple as the BASIC language that comes with the calculator, but it compiles to assembly so it's lightning fast. And you can write and build the entire game from your calculator. I spent hundreds of hours making games with Axe back in high school.” #Z80 #programming-for-everyone #calculator #PDF
